FAMILY="SANSSERIF">I am in the process of rebuilding a 1895 Model A, =
which was
done once before, but very poorly. The first thing I noticed, and the =
thing
the customer complained about, was an extremely heavy action. This was =
because
there was a lot of let off, about 1/2". When I removed the fall board, =
I
noticed that the pin block (which had been replaced), was sticking =
down from
the front stretcher about 1/4". My first inclination was that =
the plate
was set back in the piano too high, and that is why there was so much =
let
off. <BR><BR>I have replaced the pin block, and the plate is =
back in the
right position, and there is good downbearing. But I am now starting =
to work
on the action, replacing the h/s/f and wips. Now I see why there was =
so much
let off. This other rebuilder used a 1 1/2" thick pin block. But =
instead of
planing down the entire block, he only trimmed down the ends, which =
rest on
the inner rim, but he left rest of the pin block the original 1 1/2". =
That is
why there is about a 1/4" of pin block sticking down below the =
stretcher.
Obviously that wouldn't allow the action to slide in. So in order to =
get the
action in, he lowered the action by shaving down the action frame =
mounting
blocks. (I think that is what they are called). <BR><BR>I want to =
replace the
blocks. But the question I have is measurements. About 20 years ago =
when I put
a new action in a Steinway, and these blocks were not attached to the =
action
frame. I think I remember I had to sort of go by where the striking =
point was
of the last couple of notes, combined with the hieght of the hammers. =
I had a
hell of time figuring out where to put them. Is there some measurement =
I can
go by to determine where I have to put the blocks, and how high the =
action has
to be?<BR><BR>Wim</FONT> </FONT></BLOCKQUOTE></BODY></HTML>
